Calculator Prompter is a mathexpressioncalculator. You can evaluate expressions like sin(cos(tan(pi)))#2%10^3 Calculator Prompter has a built-in error recognition system that helps you get correct results: - Paste operator here; - Paste number here; - Missing '('; - Missing ')'; - Unknown symbol ... etc. With Calculator Prompter you can enter the whole expression, including brackets, and operators.You can use Calculator to perform any of the standard operations for which you would normally use a handheld calculator.

Currently, this project consists of a pure javamathexpression parser optimized for repeated evaluation. Development of an interactive 3D math visualization application based on this parser is planned for the future..
